Reading up elsewhere it would seem that you won't get the Cobra IV for free, rather you will have it unlocked. Still not 100% sure, but I'd honestly prefer it not being handed around for free; it's kind of immersion breaking to have ingame companies give away a ship for free as a reward for preordering a real world product. Unlocking is better. Plus it's a Cobra, possibly a better specced and more expensive than the III, but I doubt it'll break the bank. ATM I'm kind of assuming a between Courier and Asp price point.
